Brief analysis of DAC cable
Direct attach cable is a communication equipment connection cable. It is commonly used to realize short distance high-speed interconnected communication. It is mainly used to realize the interconnection between servers, switches, memory and other devices. It is a low-cost high speed data communication solution. The common wire specifications are 24AWG, 28AWG and 30AWG, which can meet a variety of applications.
The characteristics of DAC cable:
High performance, low cost
Real bandwidth from 1G to 10G data transmission IEEE 802.3ae and fiber channel standards are widely used, strong Integrated scheme switching capability.
Anti radiation and interference
The mechanical design and EMI design of the circular hand can effectively organize EMI electromagnetic radiation and interference.
Energy saving and environmental protection
Support hot plug, low power consumption, copper has the function of natural radiator.
EEP storage signature design
Distinguish the copper wire integration scheme and optical module cable integration scheme.
What are the advantages and disadvantages of the DAC cable compared with the active optical cable?
Advantages:
Material: The interior of the DAC cable is made of copper core. copper has the function of natural radiator, good heat dissipation, energy saving and environmental protection.
Power consumption: DAC cable has low power consumption. Because the passive cable does not need power supply, the power consumption is almost 0. The power consumption of active optical cable is generally about 440mW, DAC cable has a certain advantages in energy consumption.
Low cost: The copper price is far lower than the fiber, therefore, use DAC cable will also reduce the wiring cost for the entire data center.
Disadvantages:
Short transmission distance, heavy weight, large volume, difficult to manage.
Susceptible to electromagnetic interference, such as adverse response and degradation etc.
